IMPROVEMENT IN TIRE-TIGHTENERS.

Specification forming part of Letters Patent No. 213,412, dated March18, 1879 application tiled November 29, 1878.

To all 'whom it may concern:

Beit known that I, WILLIAM P. GooLMAN, of Kansas City, in the county ofJackson and State of Missouri, have invented certain new and usefulImprovements in Tire-Tighteners; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the saine, reference being had to the accompanyingdrawings, and to letters ot'reference marked thereon, which form a partof this specification, and in Which- Figure lis a front view of thetightener, with a spoke and section of the felly clasped thereon; Fig.2, an end view of the same; Fig. 3, a rear view thereof; Fig. 4,adctached view of the wedge, and Fig. 5 a detached view of the link.

My invention has reference to tire-tighteners; and it consists of astandard having suspended therefrom a vertically-adjustable stirrup,and, together with a wedge, adapted to be clamped to a wheel-spoke by alink, the tighteners of the clamp being increased with the resistanceoffered to the raising of the stirrup.

In the accompanying drawings, the letter A indicates the standard, thelower portion of which is grooved longitudinally on its face, as at a,and transverselyy serrated or notched on its back, as at b, while anarm, B, projects from the top of the standard at right angles to thelength thereof. From this standard there is suspended a stirrup, C, bymeans of a bolt, D, passed through an ear, c', on the stirrup, andthrough the arm B of the standard, to which it is held by a nut, d, byscrewing or unscrewing which the stirrup is elevated or lowered. Thelower ends of this stirrup are bent or cast at right angles to the facethereof, so as to form rests Aor lugs c. The other parts of thistightener consist of a link, E, and wedge F, which may taper on the topfrom the middle toward both ends, and which may have a groove, f, in thebottom thereof.

The operation of the device is as follows: The spoke is rested in thegroove of the standard, and the felly on the lugs of the stirrup. Thelink is placed around the spoke and the lower end of the standard, andthe wedge F next driven through the link over the spoke, the latter tting into the groove in the wedge, thus rrnly clamping the spoke to thestandard. The more that the nut is screwed onto the bolt the tighter thestandard clamps the spoke. The nut to the boltis then turned, andbearing against the head of the standard draws the bolt upward, therebyraising the stirrup, and the stirrup the felly, from the shoulder of thespoke, when a washer is placed between the shoulder and the felly, thustightening the tire.

Having described my invention,what I claim 1sl. A tire-tightenerconsisting of a standard and adjustable stirrup, a wedge anda link, thelink to clamp the standard and wedge to a spoke, the tightness of theclamp being increased with the resistance oii'ered to the raising ofthestirrup, substantially as set forth.

2. The combination of the standard A and vertically-adjustable stirrupC, the link E, and wedge F, substantially as set forth.

In testimony that I claim the foregoing as my own I aiiix my signaturein presence of two witnesses.

WILLIAM P. GOOLMAN.
